Abstract

PURPOSE:To eliminate the picture disturbance occurring at the switching time of the TV cameras, by setting both the TV camera which is selected presently and the TV camera to be switched next under the start state and then connecting only the pickup tube of the TV camera being selected presently to the TV picture receiver. CONSTITUTION:When main power switch 1 is made, main relay 3 is energized to close make contact 3a. And then the 1st relays 4A-4D are energized to close make contacts 4a-4d of TV cameras 5A-5D each. Then heaters 7A-7D of cameras 5A-5D are connected to resistances 8A-8D as well as to DC power sources 9A- 9D to give the heat and thus to secure the start queuing state. Then the output of a low potential is generated for a fixed time from automatic switch signal generator 10 to realize the closed circuit for the 1st-4th relay drives 11A-11D. And make contacts 18a-18d are closed by the 4th relays 18A-18D. Then only pickup tubes 6A-6D of TV cameras 5A-5D being selected presently are connected to TV picture receiver 15. Thus the picture disturbance occurring at the TV camera switching time can be prevented.
